Non-lock-up does have is advantages, like starting a load.

As far as an earlier comment made about having "lock-up in every gear", no, that's not right, at least not with Dodge transmissions.

Even a clutch on a manual NEEDS to slip to get the (heavy) loads rolling and I know for a fact that the 68RFE and ALL of it's predecessor Dodge automatic transmissions do NOT lock up in 1st gear.
In fact even the 68RFE doesn't start locking up until 4th gear.

On Again, Off Again...
 

I see you participating in this thread, so I'm going to take a known creep and liar off my ignore list just long enough to debunk some more of your BS...
NO ADVANTAGE whatsoever. Do you think a lock up converter STARTS locked? If that is what you are suggesting, you know even less about transmissions than I might've given you credit for before.
Actually, what I wrote is factually right and true. I OWN one - ZF 6HP28. You should feel my wife's 335D accelerate locked in 2nd. It is truly phenomenal - inline 3.0L 6 diesel BMW making same torque as a stock 5.9 1st gen. Ford is installing that same trans in F150s. Maybe you should read up on what Ford and BMW are installing these days. Maybe if you actually read what I wrote instead of trying to imply I wrote something I did not, I would not have to be responding to your stupid comments right now.
Thanks for clearing up that obvious bit of trivia for us. In fact, that is true. Is is also a fact that it has nothing to do with what started the discussion about lock-up vs. non-lock torque converters. If you are trying to demonstrate your knowledge of auto transmisisons you have FAILED miserably. It doesn't negate the fact that lock up converters, regardless of their gearing in terms of lock-up capabilities will ALWAYS give better average fuel mileage and run cooler. It doesn't change the fact that non-lockup converters are inferior in every way. And PLEASE correct me if I'm wrong, it does not change the fact that the answer to the OP's question is NO, unless he is willing to install a different input shaft, engine adapter, valve body and possibly some electronics depending on which Dodge model he is trying to emulate.

Maybe you can help him with that? :w2:

Thanks for proving my point! :tu:

Great, now run off to the 1st Gen board like a good little boy. Maybe Bitchie-O will stroke you over there. :lol88:

Nah, I'm here for your amusing flare ups.
Call me your Preparation-H.

Mark.

I see you are still posting in thread. I only hope it something constructive... :tu:

you got a bad tranny
 

My '93 with an auto gets 11 to 12 towing an 8,000 5th wheel. Only time I wished for a stick was coming down a long 8% grade. Trailer brakes faded, truck brakes started smelling, and by the time we got to the bottom we were moving.
The tranny was replaced at 260K miles and now has 80K on it. Oh, climbing that 8% a few days earlier, 90 plus degree temp, the tranny temp guage never got into the hot zone.
It's a good tranny in these older trucks! Your's has problems.
